Sarah Michelle Gellar Joins Twitter, 'Buffy' Castmates Welcome Her


There was an impromptu "Buffy the Vampire Slayer" reunion (on the Internet) on Tuesday when star Sarah Michelle Gellar joined Twitter, prompting her old castmates to welcome her to the madness.

Her on-screen paramour David Boreanaz (Angel) gave her a tongue-in-cheek greeting: Emma Caulfield (Anya) praised the success of Gellar's new CBS show "The Crazy Ones": Eliza Dushku -- who played Buffy's former rival, Faith -- proved that there are no hard feelings in real life, offering three pieces of advice via hashtag: "Buffy" writer Drew Z. Greenberg welcomed the star with an anecdote.

Gellar sent her second tweet on Wednesday morning, and it was about "Buffy." Be still our Sunnydale-loving hearts.

"The Crazy Ones" airs Thursdays at 9 p.m. ET on CBS.
